摘要
We investigate the influence of possible in-medium modifications of the S-11(1535) in eta photoproduction in nuclei. Besides Fermi motion, Pauli blocking, and binding effects also collisional broadening is accounted for. The in-medium width is obtained from a realistic resonance-hole model. Results on eta photoproduction are obtained from a semiclassical Boltzmann-Uehling-Uhlenbeck transport model and compared with data. We find that calculations including a momentum dependent nucleon and resonance potential are in agreement with the recent KEK data. In contrast, collisional broadening has only little influence.
